BACKGROUND ART

1. Technical Field

The present invention relates to a men's underwear suited to prevention and treatment of skin diseases of the lower abdomen of a person, especially the scrotum of the person.

2. Related Art

Conventionally, men's underwear is wholly made of cotton such as knit fabric. The cotton knit fabric is suited to absorption of sweat, but is less airy. Hence the scrotum covered with the cotton knit fabric is not sufficiently ventilated, and becomes stuffy. If the scrotum is stuffy, bacteria tend to grow and often cause skin diseases, and it is not comfortable.

The present applicant previously disclosed a men's underwear improved in ventilation in JP-A-2008-138344.

The present applicant also proposed a men's underwear capable of changing the ventilation state in Japanese Utility Model Registration No. 3149736. This men's underwear includes an opening for a body of a person, a pair of openings for legs positioned at the opposite side of the opening for the body of the person, a front body having a window formed in a portion capable of covering to the scrotum of the person, linking to the opening for the body of the person and the pair of openings for legs of the person, and a plurality of covers covering a part or the whole of the window of the front body, and provided detachably to the front body. Each one of the plurality of covers has an opening, and each opening differs in an area of the opening in every cover. One of the plurality of covers selected to be most appropriate or nearly appropriate is attached to and used at the front body.

However, in the technology disclosed in Japanese Utility Model Registration No. 3149736, a plurality of cover members must be needed in order to change the area of the opening of the cover. To change the area of the opening at small intervals, further multiple cover members should be required.

The present invention is devised to solve these conventional problems, and it is hence an object thereof to present a men's underwear capable of changing the area of openings for ventilation at small intervals, and high in satisfaction, without using a multiplicity of cover members.

SUMMARY

The men's underwear of the present invention includes an opening for the body of a person, a pair of openings for legs of the person positioned at the opposite side of the opening for the body; a front body having a window formed in a portion corresponding to a scrotum of the person, linking to the opening for the body and the pair of openings for legs, and a cover that covers a part or the whole of the window of the front body, and is provided detachably to the front body. An area of an opening of the window of the front body can be changed continuously by changing the folding state of the cover.

Moreover, the men's underwear of the present invention includes an opening for a body of a person, a pair of openings for legs of the person positioned at the opposite side of the opening for the body; a front body having a window formed in a portion corresponding to a scrotum of the person, linking to the opening for the body and the pair of openings for legs; and a cover that covers a part or the whole of the window of the front body, and is provided detachably to the front body, wherein an area of an opening of the window of the front body can be changed continuously by changing an attaching position of the cover on the front body.

According to the men's underwear of the present invention, by changing the folding state of the cover, or by changing the attaching position of the cover on the front body, the opening area of the window of the front body (an area of an effective ventilation space of the window opening) can be changed continuously. Therefore, without requiring multiple cover members, the opening area can be set to an appropriate area for a user. Hence the satisfaction for the user is enhanced.

In the men's underwear of the present invention, the scrotum of the user is covered with a covering material formed in an appropriate area of an opening. The opening is much airy as compared, for example, with the cotton knit fabric. Hence, the scrotum is prevented from getting stuffy. As a result, skin diseases of the scrotum can be prevented or treated, and the cooling effect of testicles may also be expected.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

Preferred embodiments of the present invention are described below while referring to the drawings.

First Embodiment

Referring to FIG. 1 to FIG. 8B, the men's underwear in the first embodiment is described below. FIG. 1 is a front view of the men's underwear in the first embodiment of the present invention. FIG. 2 is a front view of the men's underwear in the first embodiment of the present invention, and shows a state the cover is removed. The men's underwear 1 of this embodiment includes a front body 2, a back body 3, a pocket 4, and a cover 5. In the men's underwear 1, an opening 1 a for the body of a person, and a pair of openings 1 b for legs of the person are formed. When the user wears the men's underwear 1 of the present embodiment, the cover 5 is the portion covering the scrotum of the person.

The opening 1 a for the body of the person is a portion for passing the body of the user. The pair of openings 1 b for legs of the person are opened at the opposite side of the opening 1 a for the body of the person, and are portions for passing the legs of the user.

In the portion of the front body 2 covering the scrotum, a window 2 a for ventilation is formed (hereinafter called “window 2 a”). The shape of this window 2 a may be an arbitrary shape, for example rectangular, triangular, or circular, and the number of this window may be either one or a plurality, and these shapes and the number may be freely combined or mixed. Alternatively, the window 2 a may be formed of punching mesh consisting of vents.

The pocket 4 is attached to the front side, corresponding to the position of the window 2 a of the front body 2, and can accommodate the cover 5.

FIG. 3A to FIG. 3G are magnified views of the pocket 4 of the men's underwear in the first embodiment of the present invention. Specifically, FIG. 3A is a front view, FIG. 3B is a D-D sectional view of FIG. 3A, FIG. 3C is an E-E sectional view of FIG. 3A, FIG. 3D is an F-F sectional view of FIG. 3A, FIG. 3E is an A-A sectional view of FIG. 3A, FIG. 3F is a B-B sectional view of FIG. 3A, and FIG. 3G is a C-C sectional view of FIG. 3A. The pocket 4 is formed of two cloth pieces 4A and 4A overlapped back and forth. The edge of the pocket 4 is utilized as a sewing allowance 4 a to the front body 2, except for the upper side, and the inside portion of the sewing allowance 4 a is utilized as an accommodation unit 4 b for accommodating the cover 5.

As shown in FIG. 3A to FIG. 3G, the front and rear cloth pieces 4A and 4A of the pocket 4 are respectively provided with windows 4 c and 4 c slightly larger than the window 2 a, corresponding to the position of the window 2 a of the front body 2. The windows 4 c and 4 c are covered with an airy shielding member 6. The shielding member 6 may be formed of gauze, for example. The shielding member 6 can prevent the scrotum of the person from being exposed outside through the window 2 a, and windows 4 c and 4 c. The window 2 a is formed in a rectangular shape. The shape of the windows 4 c may be, as the same as the shape of the window 2 a of the front body, an arbitrary shape, for example rectangular, triangular, or circular, the number of window 2 a may be either one or a plurality, and these shapes and the number may be freely combined or mixed.

FIG. 4 is a magnified perspective view of the cover 5 of the men's underwear in the first embodiment of the present invention. As clear from FIG. 4, the cover 5 is formed in a caterpillar shape, and has an opening 5 a. The cover 5 is made of a cloth, and can be folded at an arbitrary position, and the area of the opening may be changed depending on the state of folding.

FIG. 5A and FIG. 5B are views of the cover 5 of the men's underwear in the first embodiment of the present invention, showing a folded state so that an area of the opening 5 a for ventilation (cutoff portion) may be maximum (100% opening state). Specifically, FIG. 5A is a view of the cover 5 as seen from the front, and FIG. 5B is a view of the cover 5 as seen from the back. FIG. 5A shows an I-I sectional view, a J-J sectional view, a G-G sectional view, and an H-H sectional view. When the cover 5 is folded as shown in FIG. 5A and FIG. 5B, it is cut off at the lower side. This cut-off portion forms an opening 5 a (the portion surrounded by double-dot chain line). When the cover 5 is put in the pocket 4 in the state as shown in FIG. 5A and FIG. 5B, it is almost overlapped with the window 2 a of the front body 2 in a front view. The area of the opening 5 a is set to be nearly equal to the area of the window 4 c of the pocket 4 and the area of the window 2 a of the front body 2 in the state shown in FIG. 5A and FIG. 5B.

FIG. 6A and FIG. 6B are development diagrams of the cover 5 of the men's underwear in the first embodiment of the present invention. FIG. 6A is a front view, and FIG. 6B is a rear view. FIG. 6A shows a K-K sectional view, an L-L sectional view, an M-M sectional view, and an N-N sectional view. At one end side in the longitudinal direction of a cover material 5′ for composing the cover 5, a rectangular cutoff 5 a′ is formed so as to correspond to the opening 5 a. At the right and left sides of the cover material 5′, hook and loop fasteners 7 and 7 are attached. The cover material 5′ is rolled like a caterpillar so that the hook and loop fasteners 7 and 7 may be opposite to each other, and the leading portion of one end side of the cutoff 5 a′ side is joined to the other end portion, and the caterpillar shape is formed. The cover 5 is folded, so that the area of the opening 5 a of the cover 5 may be as desired, and the opposite fasteners 7 and 7 are combined together, so that the cover 5 may be maintained in a desired folded state. It should be noted that, instead of hook and loop fastener 7, tape fastener or Velcro tape (trademark) may be applicable.

Since the cover 5 is made of a cloth as mentioned above, the folding position of the cover 5 may be at any desired position. FIG. 7A and FIG. 7B, and FIG. 8A and FIG. 8B show examples of changing in the folding position. For example, FIG. 7A and FIG. 7B is a magnified view of the cover of the men's underwear in the first embodiment of the present invention (50% opening state). FIG. 7A is a front view, and FIG. 7B is a rear view. FIG. 7A shows an O-O sectional view, a P-P sectional view, a Q-Q sectional view, an R-R sectional view, and an S-S sectional. In this state, the opening 5 a is a lower half of the state shown in FIG. 4, and the area of the opening is 50%. As a result, the upper half of the window 2 a of the front body 2 is covered with the cover 5. That is, the area of the opening of the window 2 a (the airy portion area of the opening of the window 2 a) is 50% of the case of FIG. 4. FIG. 8A and FIG. 8B are magnified views of the cover of the men's underwear in the first embodiment of the present invention (0% opening state). Specifically, FIG. 8A is a front view, and FIG. 8B is a rear view. FIG. 8A shows a T-T sectional view, a U-U sectional view, a V-V sectional view, an R-R sectional view, and an S-S sectional view in FIG. 8A. In this state, the opening 5 a is completely covered with the cover material 5′, and the area of the opening is 0%. As a result, the window 2 a of the front body 2 is wholly covered with the cover 5. That is, the area of the opening of the window 2 a is 0%.

FIG. 7A and FIG. 7B, and FIG. 8A and FIG. 8B are examples, and by folding the cover 5 at a desired folding position, the area of the opening 5 a may be set continuously and arbitrarily in a range from 0% shown in FIG. 8A and FIG. 8B to 100% shown in FIG. 5. The cover 5 may be also provided with graduation lines as marker of folding position. Hence, the desired folding position may be adjusted promptly. In addition, when the hook and loop fasteners 7 and 7 are separated before washing, the marker may be used by the user for remembering the desired folding position.

At the opening end portion of the pocket 4, the hook and loop fasteners 8 and 8 are attached so as to be opposite to the cloth pieces 4A and 4A. After the cover 5 is put into the pocket 4, by combined these fasteners 8 and 8 together, the opening end portion of the pocket 4 can be closed. As a result, the cover 5 which is put in the pocket 4 is prevented from slipping out of the pocket 4 during use.

According to the men's underwear 1 of the first embodiment, by changing the folding state of the cover 5, the area of the opening of the window 2 a of the front body 2 can be changed continuously. Therefore, without preparing multiple cover members, the area of the opening of the window 2 a can be set to an arbitrary area appropriate for the user. As a result, the satisfaction for the user may be enhanced.

The cover 5 covers the scrotum of the user, and it is not covered with the front body 2 of the cotton knit fabric. Hence, being different from the state covered with the cotton knit fabric, the scrotum is sufficiently airy. Therefore, the scrotum is prevented from getting stuffy extremely, and skin diseases due to growth of bacteria can be prevented, and the treatment may be promoted.

The shape of the opening 5 a of the cover 5 may be, as the same as the shape of the window 2 a, an arbitrary shape, for example rectangular, triangular, or circular, and the number of this window may be either one or a plurality, and these shapes and the number may be freely combined or mixed.

The cloth pieces 4A and 4A of the pocket 4 may be (1) both cloth pieces 4A and 4A made of cloth, (2) both cloth pieces 4A and 4A made of mesh, or (3) one cloth piece 4A made of cloth, and the other cloth piece 4A made of mesh. Alternatively, (4) the cloth material of the front body 2 side may be used by the front body 2 itself, and the other cloth material 4A may be made of cloth, or (5) the cloth material of the front body 2 side may be used by the front body 2 itself, and the other cloth material 4A may be made of mesh. Herein, the mesh may be made of gauze or the like.

As a second example of the first embodiment, without using the shielding member on the widows 4 c and 4 c of the pocket 4, as shown in FIG. 9 (a development diagram of the cover of the men's underwear used in the second example of the first embodiment of the present invention), a shielding member 6 may be attached to the portion of a cutoff 5 a′ of the cover member 5′.
